930a1434ac Add lvm_vg_* APIs to create and modify VGs.
Add some liblvm APIs for VGs.  Most of these APIs simply call into the internal
liblvm library.  Ideally we should call the liblvm functions directly from
the tools.  However, until we convert more of the code to liblvm functions,
things like the cmd_context will get in the way.  For now just implement the
liblvm functions as wrappers around the internal functions, with a little
error checking and return code handling.  We put all these vg APIs into a
new file, lvm_vg.c

The following APIs are implemented:
lvm_vg_create, lvm_vg_extend, lvm_vg_set_extent_size, lvm_vg_write,
lvm_vg_remove, lvm_vg_close.

Still TODO:
- cleanup error handling by using lvm_errno() and related APIs
- cleanup naming / clarify which functions commit to disk vs not
- implement more 'set' functions
- decide on 'set' / 'change' nomenclature

9c5a7b0481 Add default cmd->cmd_line initialization for liblvm lvm_create().
This needs initialized to non-NULL before using the archive() call.
Normally this is set to the cmdline string when lvm is called from a tool.
We could think about using it in another way, as a potential audit trail
of liblvm calls, or just leave it set to the default "liblvm", similar to
what clvmd does.  For now, just set it to "liblvm".

39d6ccdfc7 Define handles to liblvm objects for pv, vg, lv, lvseg, pvseg.
Define the 5 main liblvm objects to be the pv, vg, lv, lvseg, and pvseg.
We need handles defined to all these objects in order for liblvm to be
equivalent to the reporting commands pvs, vgs, and lvs.

- move vg_t, lv_t, and pv_t from metadata-exported.h into lvm.h
- move lv_segment and pv_segment forward declarations into lvm.h
- add lvseg_t and pvseg_t to lvm.h

NOTE: We currently have an inconsistency in handle definitions.
lvm_t is defined as a pointer, while these other handles are just
structures.  We should pick one scheme and be consistent - perhaps
define all handles as pointers (this is what I've seen elsewhere).

470304e2a2 Remove unnecessary includes in lvm_base.c.
We would like to declare our handles pv_t, vg_t, and lv_t in
the external library header lvm.h.  However, these are already
defined in metadata-exported.h for the use of some of the
in-progress liblvm APIs.  Thus, we cannot both define
them in lvm.h and include metadata-exported.h in the external
library C files.  We could use preprocessor tricks (#ifndef)
but for now we just avoid the include.

e0c64c6c35 Add new liblvm build directory and move lvm_base.c.
The original liblvm.a has been moved to liblvm-internal.a.
We now use liblvm.a for the new application library and build
it inside liblvm directory.

Change dependencies so tools depend on liblvm application library,
and application library depends on liblvm internal.
